'Justified' adds Patton Oswalt for Season 4

Comedian
Patton Oswalt will head to Harlan for a recurring part on Season 4 of
"Justified."

Oswalt will play Bob Sweeney, a high school classmate of Raylan's (
Timothy Olyphant) who's now a local constable,
TVLine reports. Raylan hires him to look after Arlo's (
Raymond J. Barry) house while the old man is incarcerated.

Oswalt has done his share of drama work in the past -- he starred in the rather disturbing movie
"Big Fan" and has guested on
"Caprica" and
"Dollhouse" -- but Bob will have his comedic moments as well. He never tires of retelling his one great football story from high school, and he has a
"go bag" at the ready in case doomsday strikes.

In the season premiere, he and Raylan team up to track down a fugitive.

Season 4 of "Justified" begins filming later this month and will be back on FX in early 2013.
